fix: use deno run for init instead of deno create before 2.3.0 (#3746)

## Summary
- Reverts all references from `deno create @fresh/init` back to `deno
run -Ar jsr:@fresh/init` across docs, READMEs, homepage, and CLI help
text
- Removes the deprecation warning in `packages/init/src/mod.ts` that
told users to switch to `deno create`
